About the Trapezoid Area Calculator

A trapezoid's area is found by averaging its two parallel sides (bases) and multiplying by the height between them. Each base and the height have their own unit selector, and so does the area result, so you can mix units freely.

Formula: Area = ((base₁ + base₂) ÷ 2) × height
